  • Page 4: Introduction

    1. INTRODUCTION This Installation Manual is intended for professionals, qualified to install KLASIK air handling units. Quali- fied professionals are people with sufficient professional experience and knowledge of ventilation systems and installation thereof, knowledge of electrical safety requirements and having ability to perform works without endangering themselves or others.

  • Page 5: Unit Types And Sizes

    The unit may fail to reach a user-defined supply air temperature when the actual temperature in the premises differs significantly from the temperature set point, since this will lead to inefficient operation of a heat exchanger.

  • Page 6 All KLASIK air handling units are divided into 3 groups according to the type of recuperator (heat ex- changer) used: KLASIK R – air handling units with rotary heat exchangers. Rotating wheel (rotor) of a rotary heat ex- changer collects heat or cold from the indoor air and transfers it to the fresh supply air. Recovered heat/ cold capacity is changed by adjusting the rotor speed.
  • Page 7 KLASIK RA – air handling units with a liquid coupled heat exchanger that uses a liquid heat carrier for heat exchange. The heat exchanger consists of two coils (in the supply and extract air flows) connected via a circulation pipework unit (sold separately) and filled with a non-freezing heat carrier, usually a mixture of water and glycol.

    Air filters are intended for removing dust, bacteria and other fine particles from the supplied and ex- tracted air. KLASIK air handling units may be fitted with various types of filters (bag, compact, Hepa). Also, filters can have different filtration classes , i.e.

    1.3.2. Fan section KLASIK R, CF and RA air handling units have two fan sections. In KLASIK S air handling units there is one fan section. Depending on the unit size, it may be several fans integrated into one fan section. Fans are con- nected to an electronic circuit board fitted in the same section.

    ANNEX NO. 1. ADJUSTMENT OF THE ROTARY HEAT EXCHANGER WHEEL In the KLASIK 8 and larger units, a large-diameter rotary heat exchanger is used. Since, during the op- eration, the airflow constantly pushes the rotor wheel, due to its dimensions, to one side, it can eventually distort, causing the rotor sealing brushes and axle bearings to wear out faster or even may jam after time.
